Line pipe tray

ABSTRACT

A line pipe tray for supporting a line pipe has outer sidewalls operatively coupled to outer end walls, inner sidewalls operatively coupled to the inner end walls, and a bottom surface extending between the inner sidewalls and the inner end walls to form a basin. The tray can further include pipe saddles on the top edges of the end walls and sidewalls. The tray can further include a pour lip on the end wall pipe saddles, and a recess on the end walls for receiving a pail or fluid container. Lifting handles disposed through the end walls can further include a tab for hooking onto a pail or fluid container to keep it from slipping away when the tray is lifted and tilted to pour fluids from the basin into the pail or fluid container.

CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation U.S. patent application Ser. No. 13/546,019 filed Jul. 11, 2012, which claims the benefit of U.S. Provisional Application No. 61/603,627, entitled “Line Pipe Tray”, filed Feb. 27, 2012, and hereby incorporates the same by reference herein in their entirety.

TECHNICAL FIELD

The present disclosure is related to the field of trays used to support pipe, in particular, trays used to support line pipe to or from a producing well, and that further comprise a basin for catching fluids that can spill from a union joint on the pipe.

BACKGROUND

Line pipe trays are known. They are typically rectangular in structure, when viewed from the top, and can comprise upstanding walls on each side, forming a basin therebetween and therein. They can further comprise saddles disposed on an upper edge on the upstanding walls to cradle line pipe lying thereon. Such line pipe trays are designed to support a singular size of pipe. The line pipe can be used to carry produced substances from a well, or to carry fluids or gases, such as steam, to a well in aid of operations being conducted on the well, as well known to those skilled in the art.

Typically, line pipe trays can be placed on the ground underneath union joints between adjoining pieces of line pipe to support the pipe off of the ground. When a union joint between adjoining pieces of line pipe is uncoupled, any fluids in the pipe can flow out of the ends of the pipe. By having a line pipe tray beneath a union joint, the tray can catch the released fluids. The captured fluids can then be dumped from the tray into another container or storage device for reuse, recycling or disposal, as required.

Current designs of line pipe trays can be flimsy and not structurally sturdy to withstand the weight of the pipe they support or the fluids captured and/or may be physically difficult to handle or move so as to pour the fluids in the basin of the tray to another container.

It is, therefore, desirable to provide a line pipe tray that overcomes the shortcomings of prior art designs of line pipe trays.

DETAILED DESCRIPTION OF EMBODIMENTS

An improved line pipe tray is provided. Referring to FIGS. 1 to 6, an embodiment of line pipe tray 10 is shown. In some embodiments, line pipe tray 10 can comprise substantially parallel opposing outer sidewalls 12 and substantially parallel opposing end walls 14, and complimentary inner sidewalls 20 and inner end walls 26 that can intersect and adjoin outer sidewalls 12 and outer end walls 14 along top edge 30. In some embodiments, line pipe tray 10 can comprise traction rib 18 disposed therearound along a lower edge of outer sidewalls 12 and outer end walls 14 to provide stability and structural strength to line pipe tray 10, and to provide grip or traction in multiple types of ground conditions such as ice, snow, mud, dirt, grass and gravel. In some embodiments, outer sidewalls 12 and outer end walls 14 can taper inwardly towards each other from traction rib 18 to top edge 30, to provide additional stability and structural strength to line pipe tray 10.

In some embodiments, line pipe tray 10 can further comprise outer corner walls 16 operatively coupling outer sidewalls 12 to outer end walls 14, and inner corner walls 28 operatively coupling inner sidewalls 24 to inner end walls 26, wherein outer corner walls 16 and inner corner walls 28 intersect and adjoin along top edge 30. In further embodiments, traction rib 18 can extend along a lower edge of outer corner walls 16, and outer walls 16 can taper inwardly from traction rib 18 to top edge 30. In some embodiments, outer walls 16 provide chamfered corners to line pipe tray 10, at approximately 135 degrees relative to both of outer sidewalls 12 and outer end walls 14, to provide additional stability and structural strength to line pipe tray 10.

In some embodiments, line pipe tray 10 can comprise substantially planar bottom surface 22 extending between inner sidewalls 24, inner end walls 26 and inner corner walls 28 to form basin 20 therebetween. In some embodiments, line pipe tray 10 can further comprise pour channel 42 disposed on one or both of inner end walls 26 tapering outwardly from bottom surface 22 to top edge 30, thereby forming channel edges 44 disposed between end walls 26 and pour channel 42. In some embodiments, pour channel 42 can be configured or tapered for pouring fluids of high viscosity. In some embodiments, pour channel 42 can be configured or tapered for pouring fluids of low viscosity.

In some embodiments, line pipe tray 10 can comprise pipe saddles 32 disposed on outer and inner end walls 14 and 26 along top edge 30. In some embodiments, one or both pipe saddles 32 can further comprise pour lip 38 that can intersect with pour channel 42 wherein pour lip 38 can be configured to rest upon, and pour into, a secondary fluid container, such as a pail, when fluids are poured out of basin 20 along pour channel 42. In some embodiments, pipe saddles 32 can be configured to support the weight of 6.5 inch heavy gauge pipe or lower.

In some embodiments, line pipe tray 10 can comprise outer pipe saddles 34 disposed on opposing outer and inner sidewalls 12 and 24 along top edge 30. In some embodiments, outer pipe saddles 34 can be configured to support the weight of 4 inch heavy gauge pipe or lower. In some embodiments, line pipe tray can further comprise middle pipe saddles 36 disposed on opposing outer and inner sidewalls 12 and 24 along top edge 30, and disposed between outer pipe saddles 34. In some embodiments, middle pipe saddles can be configured to support the weight of 5 inch heavy gauge pipe or lower.

In some embodiments, line pipe tray 10 can comprise one or more lifting holes or handles 52 disposed through one or both of outer end walls 14, as shown in FIGS. 1, 3, 4 and 5 that allow personnel to lift and/or move line pipe tray 10. In some embodiments, lifting holes 52 can be d-shaped in configuration although it is obvious to those skilled in the art that lifting holes 52 can comprise any suitable shape for lifting. In some embodiments, line pipe tray 10 can comprise lifting hole or handle 46 disposed through one or both of outer end walls 14. In some embodiments, lifting handle 46 can be disposed between lifting handles 52.

In some embodiments, line pipe tray 10 can comprise recess 48 disposed on one or both of outer end walls 14. Recess 48 can be a concave depression formed on outer end wall 14 to allow line pipe tray 10 to be placed immediately beside a fluid container or pail prior to pouring fluids from basin 20. In some embodiments, lifting handle 46 can be arc-shaped, and can further comprise tab 54 disposed therein, wherein tab 54 can be used to hook onto a container or pail to prevent the pail from sliding away from line pipe tray 10 when it is lifted and tilted to pour fluids from basin 20 into the pail. Referring to FIG. 7, line pipe tray 10 is shown in a lifted and tilted position relative to pail 56 to pour fluids 60 from basin 20 into pail 56. Lip 58 of pail 56 is inserted into lifting handle 46, and pail tab 54 is shown hooked onto lip 58 to prevent pail 56 from sliding away from line pipe tray 10 as fluids 60 are being poured over pour lip 38 into pail 56.

In some embodiments, line pipe tray 10 can be comprised of high molecular weight plastic, which can be more resistant to ultra-violet light and can further allow line pipe tray 10 to last longer in outdoor conditions than other types of plastic, and can provide better flexibility. In some embodiments, line pipe tray 10 can be comprised of carbon fibre, fibreglass, composite materials or a combination of any or all of the materials disclosed herein.

In some embodiments, line pipe tray 10 can be manufactured using rotational plastic manufacturing techniques, as well known to those skilled in the art. In some embodiments, line pipe tray 10 can be further configured such that multiple line pipe trays 10 can be stacked together when not in use.
